Life among the monkey hunters: The Amazon tribe that has evolved flat feet after years of catching primates to eat by climbing trees and shooting them with blowpipes

The Huaorani tribe - there are only 4,000 of them - live a simple life in the rainforests of eastern Ecuador They live off the land, shooting blowpipes to kill monkeys, which they then skin and roast over open fires They also eat peccary pigs and toucans as well as plants and herbs which they have foraged in the forests Their lifestyle has led to their feet evolving - most have very flat feet, which help them to climb the trees In 1990 the Ecuadorean government set up the Waorani Ethnic Reserve to protect the forest they live in Photographer Pete Oxford said: 'One of my greatest joys is spending time with people unlike myself'
